This commit takes care of stack randomization and stack guard gap when
computing mmap base address and checks if the task asked for randomization.
This fixes the problem uncovered and not fixed for arm here:

by using is_compat_task in arch_mmap_rnd, it allows more genericity and

This series introduces generic functions to make top-down mmap layout
easily accessible to architectures, in particular riscv which was
the initial goal of this series.
The generic implementation was taken from arm64 and used successively
by arm, mips and finally riscv.

The Linux kernel for powerpc since v3.9 has a bug in the TM handling where any
unprivileged local user may crash the operating system.
This bug affects machines using 64-bit CPUs where Transactional Memory (TM) is
not present or has been disabled (see below for more details on affected CPUs).
There are several places in the kernel where it is necessary to
check whether a device is a pci untrusted device. Add a helper
to simplify the callers.
